DEVICE.

I Patented July 16, 1907.-

Application filed March 28, 1906. Serial No. 808,585.

Be it known that I, WILLIAM B. Runoxnn'r, a citizen of the United States, and a resident or Ridgefield, in the countyof Bergen and Stateof New Jersey, have invented certain new and useful Improvements in Spring Devices, of which the following is a'specification.

My invention relates to spring devices such as the so- 1 called shock absorbers applied to automobiles; and it I I has for'itsobject to provide a spring device in which the springs shall be subject to compression whether the ends or heads'be forced apart or towards each other, said v springs in their normal condition, when not acted upon by extemal for'ces, being under a predetermined com- For thispurpose my invention consists essentially in the arrangement of two movable spring heads; two spring'guide bolts secured by their ends to one of the spring heads and extending freely through the opposite whereby, both in forcing'said connecting heads apart.

spring. head and provided with stops; a spiral spring about each of said spring guide bolts andheld between saidspring heads; a guide bolt passing freely through both spring heads and provided with an upper and a :low'er stop; a lower connecting head secured to said guide bolt; and an upper connecting head held between the spring head and the stops of said spring guide bolts or towards each other, the said spiral springs are pompressed..."

i The. nature of my invention will be best understood when described in connection with the accompanying drawings in which- Figure 1 is a front elevation showing the spring devicelin normal position. Fig. 2 is a front elevation showing the two opposite connecting heads forced apart. Fig. 3 is a similar view-showing the two opposite connecting heads forced towards each other. 4 isa side elevation.

Fig. Fig; 5 is a top view. Fig. 6 is a I view illustrating my improved spring device applied to ',the spring and frame of a vehicle.

l Similar characters of reference-designate corresponding parts throughout the several views. 4

' Referring now'to the drawings, 10 and 11 are the uppcr and lower spring heads which consist of a cross bar provided with two recesses each adapted to receive a spiral spring 12. These springs are placed about two spring guide bolts 13, the lower ends of which are secured to the lower spring head 11 but whose upper ends 13 and freely through the upper and lower spring heads "and'is provided with suitable upper and lower stops 17.

. To the lower end of this bolt is hinged a lower securing or connecting h'ead 18 adapted to secure the spring device to a suitable support. v

device located between the frame 19 and-the spring 20 of an automobile or similar vehicle, the upper head 14 being secured to the frame 19 and the lower head 18- to the spring 20. The spring device is thus in a neutral position under. a .predetermined compression, and during normal conditions does not come into action. During sudden shock, however; when the frame 19 and the spring 20 are either forced apartor toward each other the said insertedl'spring device comes into action compressing in either case, asshown in Figs. 2 and 3 respectively.

If the distance between the supports be increased as in Fig. 2 the upper spring head 10 is drawn down by the bolt 16 as shown, thereby compressing the springs 12 against the lower spring head 11 which is held to the updistance between the supports be decreased as in Fig. 3 the lower spring head 11 is forced up toward the upper spring head 10 which is held by the upper connecting head 14 as shown, thereby compressing the springs 12 as before. The springs 12 are therefore compressed in either case, and I have found that their life is greatly prolonged by causing them to act in one direction only.

Although I have used the terms upper and lower with the spring heads and connecting heads, it does not follow that in actual use the device may not be used in other positions, as my invention consists essentially of a spring device comprising two movable spring heads, guide bolts, a spring or springs held. between said spring heads and an upper and a lower connecting head so arranged that the said spring or springs are subjected to compression whether the connecting heads be forced apart or brought together.

What I claim as new and desire to secure by Letters Patent of the United States is:

1. In combination with a-vehicle spring, asprlng device secured to said vehicle spring and to the frame of sald vehicle and comprlslug an upper and .a lower movable connecting head, said heads being adapted to approach and recede from each other, a guide bolt, two spring heads movable relatively to said guide bolt and adapted to each approach and recede from the other, and a spring, or springs between said spring heads.

2. A spring device comprising an upper and a lower movable spring head; two side sprlng guide bolts; two spiral springs about said sprlng guide bolts and between head 11. A guide bolt 16 passes between the two bolts per connecting. head 1.4 by the spring bolts 13. If the In Fig. 6 I have shown the above described spring throughout the specification and claims in connection said upper and lower s pring heads; a guide boltiau upper connecting hood adapted to act against said spging guide' bolts; and a loweiconnecting head hing edfto said guiiie bolt.

3. A spring device comprising an uppf and a l i'ier held between the said upper and lower spring heads; a. guide bolt passing freely throughboth' of said spring u pper' onnecting head held'between the upper spring head ond the stops of said s ring guide bolts.
